Opslagtiering

Opslagtiering is a process in inventory management that classifies stock into tiers to tailor storage, replenishment and handling policies. The aim is to align stock levels and service requirements with the importance or turnover rate of items, thereby optimizing space, capital and operational efficiency. While the term is common in Danish and Norwegian contexts related to physical inventory, the principle also appears in related fields such as IT storage, where data can be tiered by access patterns and cost.

A typical approach uses classification schemes like ABC analysis to create Tier 1, Tier 2 and Tier 3 categories. Tier 1 items are fast-moving or high-value and often have strict service level targets; Tier 2 items have moderate turnover; Tier 3 items are slow-moving or low-value. For each tier, policies define target stock levels (including safety stock), replenishment frequencies and appropriate storage locations within the warehouse.

The practice offers several benefits, including improved service levels, reduced stockouts, more efficient use of space and working capital, and streamlined replenishment planning. It also presents challenges, such as maintaining accurate data, adapting to demand volatility, and ensuring proper integration with enterprise resource planning or warehouse management systems. Regular review and adjustment of tier definitions are essential to keep the system aligned with changing demand and capacity.

Examples include placing Tier 1 SKUs in easily accessible locations near packing areas and reserving Tier 3 items for more distant shelves or offsite storage. Opslagtiering is therefore a practical method to optimize inventory performance across supply chains.
